And again he said,
To what shall I liken the kingdom of God?
Read Chapter 13
Ambrose of Milan
AD 397
There are three measures: of the flesh, of the soul and of the spirit. This is truer of the spirit in which we all live…. The woman, who prefigures the church, mixes with them the virtue of spiritual doctrine, until the whole hidden inner person of the heart is leavened and the heavenly bread arises to grace. The doctrine of Christ is fittingly called leaven, because the bread is Christ. The apostle said, “For we, being many, are one bread, one body.” Leavening happens when the flesh does not lust against the Spirit, nor the Spirit against the flesh. We mortify the deeds of the flesh, and the soul, aware that through the breath of God it has received the breath of life, shuns the earthly germs of worldly needs. –.
The grain of wheat is Christ, because he was spiritual leaven for us, and many think that Christ is the leaven that enlivens the virtue which we have received. Since the leaven in the flour surpassed its own kind in strength and not in appearance, Christ was preeminent among the fathers, equal in body, incomparable in divinity. The holy church is prefigured in the woman in the Gospel. We are her flour, and she hides the Lord Jesus in the inner parts of our mind until the radiance of heavenly wisdom envelopes the secret places of our spirit.
A woman took some yeast when the church, by the Lord’s generosity, secured the energy of love and faith from on high. She hid this in three measures of flour until the whole batch was leavened. She did this when she performed her ministry of imparting the word of life to parts of Asia Minor, Europe and Africa, until all the ends of the world were on fire with love for the heavenly kingdom.
The leaven is small in quantity, yet it immediately seizes the whole mass and quickly communicates its own properties to it. The Word of God operates in us in a similar manner. When it is admitted within us, it makes us holy and without blame. By pervading our mind and heart, it makes us spiritual. Paul says, “Our whole body and spirit and soul may be kept blameless in the day of our Lord Jesus Christ.” The God of all clearly shows that the divine Word is poured out even into the depth of our understanding…. We receive the rational and divine leaven in our mind. We understand that by this precious, holy and pure leaven, we may be found spiritually unleavened and have none of the wickedness of the world, but rather be pure, holy partakers of Christ.
